ABSTRACT:
A recorder for monitoring the operation of a cardiac pacemaker and the response of the patient to the pacemaker includes a recorder module which receives a composite signal including an ECG signal, a pacemaker spike having a frequency spectrum that lies substantially at frequencies greater than the frequency band required to pass the ECG signal, and further includes artifact noise within the frequency spectrum of the pacemaker spike. The recorder module distinguishes the pacemaker spike from the artifact noise and upon recognizing the pacemaker spike, the recorder module produces a distinctive synthesized signal whose frequency spectrum lies substantially within the frequency band required to pass the ECG signal so that the synthesized signal will pass through the pre-emphasis filter that is used to reject artifact noise and will then be recorded.
